Benefits of technology

The present invention provides a backwater gate valve assembly that automatically moves a gate valve between open and closed positions based on the level of fluid in the valve. The valve body includes a chamber with an inlet opening and an outlet opening, and a fluid level sensor that detects a predetermined level of fluid in the chamber and sends a signal to a controller. The controller then moves the gate valve between the open and closed positions. The valve is supported in the interior chamber and is movable between the open and closed positions. The valve can be moved manually or by an actuator. The invention provides a more efficient and reliable backwater gate valve assembly for controlling the movement of fluid in a system.

Problems solved by technology

While backwater valves are known, such valves are manual in operation and requires attention in the event of a prolonged backup of effluent into the valve.

Embodiment Construction

[0041]As used in the description that follows, directional terms such as “upper” and “lower” are used with reference to the orientation of the elements as presented in the figures. Accordingly, “upper” indicates a direction toward the top of the figure and “lower” indicates a direction toward the bottom of the figure. The terms “left” and “right” are similarly interpreted. The terms “inward” or “inner” and “outward” or “outer” indicate a direction that is generally toward or away from a central axis of the referred to part, whether or not such an access is designated in the figures. An axial surface is therefore one that faces in the axial direction. In other words, an axial surface faces in a direction along the central axis. A radial surface therefore faces radially, generally away from or toward the central axis. It will be understood, however, that in actual implementation, the directional references used herein may not necessarily correspond with the installation and orientatio...

Abstract

A backwater gate valve assembly having a gate valve movable between a closed position where the gate occludes an outlet opening and an open position where the gate valve does not occlude the outlet opening. The gate valve is coupled to a motorized actuator that is configured to move the gate valve between the open and closed positions upon sensing of a predetermined level of water in the body of the backwater gate valve assembly.

Description

BACKGROUND1. Field of the Invention[0001]The present invention generally relates to water valve assemblies. More specifically, the invention relates to a backwater valve assembly that incorporates an in-line, shut-off gate valve.2. Description of Related Art[0002]Backwater valve assemblies are devices that permit the free flowing of fluid in one direction. If a reverse flow of the fluid occurs as a result of downstream backpressure or blockage, for example, the backwater valve assembly may be closed to prevent flow in the reverse direction. Accordingly, backwater valve assemblies have a broad range of applications, including preventing the backing up of sewage or waste water into a building as a result of a downstream blockage in a storm water or sanitary sewer drainage system.[0003]While backwater valves are known, such valves are manual in operation and requires attention in the event of a prolonged backup of effluent into the valve.SUMMARY[0004]In overcoming the various drawbacks...
